INVENTOR WITNESSES ROLAND E. CHATTAWAY, OF BROOKLYN, NEW YORK.

CLOTHES-LINE PULLEY.

Specification of Letters Patent.

Patented May 30, 1916.

Application'filed September 24, 1915. Serial No. 52,518.

To all whom it may concern Be it known that I, ROLAND E. CHATTA- WAY, a citizen of the United States of America, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in- Clothes-Line Pulleys, of which the following is a specification.

' This invention relates to improvements in clothes line pulleys, and aims to provide improvements therein. v

It is the purpose of the present invention to provide an easy running pulley for clothes lines (preferably ball bearing), in which the running parts are'protected from the weather, and'which is durable, simple in construction, and cheap to manufacture.

Other specific features of improvement will be referred to hereinafter.

The invention will be more clearly described in connection with the accompanying drawings, illustrating, two embodiments,

wherein I Figure 1 illustrates an elevation of one of the embodiments; Fig. 2 is a bottom plan view of the construction shown in Fig. 1;

. Fig. 3 is an end view of said construction;

Fig. 4 is a vertical cross section; Fig. 5 illustrates a detail of the casing and bearing; Fig. 6 illustrates a side elevation of a second embodiment; and Fig. 7 is a top plan view of the construction illustrated in Fig. 6.

In said drawings A designates the casing of the pulley, which is preferably constructed of two pressed or cast metal parts or shells a a The shells a a are conveniently fastened together by means of rivets a B designates the pulley wheel. The wheel is preferably mounted upon ball bearings. The ball bearings preferably comprise a plurality of balls I), a pair of cupped rings 6 forced into recesses on opposite sides of the wheel B, and a pair of cones b 6 The cones b have polygonal bases which fit within the polygonal recesses b in the inner sides of the shells or parts a a of the casing A. The recesses in the casing position the cones, and prevent them from turning. Moreover, the weight or strain on the wheel is transmitted through the cones b to the casing A. The cones b ,are preferabl bored and fit upon a shaft 6 the ends 0 which are received in recesses b in the parts a a v of the casing A. The shaft 6 has shoulders I) thereon spaced the proper distance apart of the cones, and the cones are held in position by the fit of the polygonal ends of the in and out of the casing. The tubular openings a and a are preferably flared outwardly, whereby the rope, even when it sags, w1ll not rub against thecasing, especially the sharp edges thereof.

In cold and wetfweather ice and snow accumulate upon the' rope, and when the rope makes a sharp bend, as in passing over the pulley, much of the ice breaks and becomes detached from the rope. To prevent this detached ice choking the runway through the casing, an opening a is provided in the bottom of the casing, through which opening the detached ice may fall.

An eye a is preferably attached to the casing. This eye servesfor attaching the pulley to a support. The eye is preferably provided with a shank a which is tapered and squared and fits in a correspondingly formed recess a in the casing. The recess a is preferably formed in the two parts of the casing a and a partly in one and partly in the other. The tapered and squared form of the shank holds the eye in the casing, closes the recess against the weather, and prevents the eye from turning. The casing furthermore, may be provided with an opening a, in addition to the against the shoulders on the spindle on their inner ends are held in position and serve to space the wheel and prevent its hitting the casing.

Changes may be made in the constructions a casing and a wheel within said casing,

said casing having openings for the running in and out of the line, an opening above said wheel and an opening below said wheel through which particles of ice detached from the line may fall, and a cover for said'upper opening.

3. A pulley comprising a casing and an attaching eye, said attaching eye having a squared and tapered shank, said casing having a squared and tapered recess therein in which said shank fits, and said casing having an opening formed in its lower part.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
